Specification of Letters Patent. Patented Sept. 17, 1918.

Application filed February 20, 1918. Serial No. 218,262.

To all whom it may concern Be it known that I, RICHARD BABCOCK, acitizen of the United States, residing at Barcroft, in the county ofAlexandria and State of Virginia, have invented certain new and usefulImprovements in Fastening Means, of which the following is aspecification.

This invention relates to fastening means or connecting devices, andresides especially in the means for readily fastening or anchoring thelinks of a chain or part or parts of some element or elements, and inprovision for locking said means in normal position.

The invention hereinafter set forth and described is intended primarilyfor use in attaching anti-skidding chains, of the fixed point oranchored type, to the felly or other part of an automobile truck wheel.ever, the invention may be embodied in a number of forms to be fixed inposition in primarily intended for use with anti-skidding devices, asabove mentioned, it can be used equally well for a great variety ofpurposes.

The primary object of the present invention is to provide a plate with apivotally mounted bar having oppositely disposed arms at ends, whicharms, are adapted to re ceive ordinary twisted chain links and havetheir ends received in recesses in said plate when said bar is in normalposition.

A further object is to provide means for releasing said bar and forlocking 1t in nor- 1 mal position, the arrangement and construction ofthe parts being so calculated as to throw the minimum amount of strainon said means when all parts are in normal position with ananti-skidding, or other, chain or chains applied to the arms.

A further object is to provide sufficient clearance between the arms andthe plate to allow the chain links, or other elements, to he slippedover the ends of the arms.

A further object is to so form the bar, plate and releasing and lockingmeans that the three elements will constitute a self-contained unit, nopart of which can become separated, by manipulation by hand or with anyordinary tool, and so become lost. Quite commonly persons operatingtrucks are not mechanically inclined and might separate the partswithout need and then lose one or more of the parts. With this fact inview How-V it is desirable to so after being assembled difiicult toseparate.

In the accompanying drawings, in which only the preferred form isillustrated;

Figure 1 represents a perspective view of a device embodying theinvention; I

Fig. 2,. a plan View thereof; I V

Fig. 3, a cross sectional view on the line 33 of Fig. 2; and

Fig.4, a cross sectional view on the line 44L of Fig. 2, looking in thedirection of the arrows.

Referring now in detail to the drawings,

A indicates the plate having at each end and on opposite sides aperforated lug B through which any suitable fastening device, such as abolt or lag-screw, not shown, may be passed to fasten the plate to thefelly of a truck wheel or to any other relatively fixed object.

. This plate .A is provided at each end and on opposite sides with apreferably recessed lug preferably formed integral with the plate,eachlug extending preferably about three-fourths of the length of theplate and toward, the other end thereof.

1 designates one of these lugs, which is preferably plain and solid,except for its recess 3 and 2 designates the other of said lugs, whichisalso preferably plain except for its recess 3 and a slot 4 extendingthrough said lug and transversely thereof.

The portion of said plate between said lugs ,1 and 2 is provided with apreferably integral raisediOl long portion or'shoulder 5 and is providedat its central point with a perforation throughwhich passes a pivot pin6. v

A- spacing collar 7 is slipped over the upper end of pin 6, the bar 8 isthen slipped form the parts that and finished they are over the upperend of said pin and the ends 7 ofthe pin are then upset or spread, asclearly-shown in Fig. 3, leaving, however, sufficient play to permit theturning or pivoting of the bar 8 thereon.

- A releasing and locking bolt 9 is inserted in the slot 4 and has itsinner end bifurcated to receive between the bifurcations 10 thereof aportion of the bar 8, which portion of said bar and the bifurcations 10are perforated to receive a pivot pin 11, the ends of which are upset orspread for obvious reasons.

The outer portion of this bolt 8 is screwthreaded a receive awing-nut12, which is preferably round and of sufiicient size togenerouslyspan the slot l. After'the nut has been screwed on theouter-portion of bolt 8 the extreme outer end thereof will be preferablyupset or spread as at 13 to prevent the separation of the nut 12therefrom.

The bar 8 above referred to is provided on each end with an arm 14, saidarms being disposed in reverse directions and having their outer endsreceived, in normal position, in the respective deep recesses 3 in therespective lugs l and 2. The opposing faces of said arms are eachprovided with a recess 15, the deepest point of which lies on thecentral longitudinal line of said plate A, which line also passesthrough) the axis of pin 6, so that the terminal links G of the chain orchains or other element or elements will engage the arms at this pointand pull in diametrically opposite directions, throwing practically allthe strain on the arms 14,

bar 8 and plate A and putting practically no strain on the: pin 6 andthe bolt 9 with its bifurcations 10 and the pin 11.

In operation, to apply the chain links G.- or other elements to beconnected, fastened will be unscrewed or anchored, the nut l2sufficientlyto allow the bar 8 to be, turned on pin 6 until the ends ofarms 14: lie on the longitudinal central line of plate A, when the linksC may be slipped over the ends of said arms 14a The nut 8 will then bescrewed up on. the bolt 9 until: the ends of said'arms 14E are heldfirmly against the inner walls of the recesses 3. Toremove the links Cthe same operation is repeated, exceptthat the links C are withdrawnfrom the arms-instead of being applied thereto, and the only reason fortightening the nut 8 then will be to prevent rattling.

The slot 4 is of course,

sions to allow the inner end of the bolt 9 to describe an arc ofsufficient magnitude to allow the ends of arms 1 L to lie on thelongitudinal' central line of. plate A, with pin 6' as the center ofsuch arc.

It is obvious, of course, that in case the arms 14 or bar 8 shouldbecome stuck in,

normal position, by ice or other foreignv matter, it may be quicklyfreed by tapping the free end of the bolt 9.

The bar- 8 with its arms 14 will preferably be of drop-forged steel,though any suitable material may be used for this part as well as anyother parts of the device.

Having thus described my invention, what (topics of this palcnt may beobtained for of sufiicient dimen-- l claim as new and desire to secureby Letters Patent is:

1. A plate provided with a recessed lug on each end and on oppositesides, in combination with a pivotally mounted bar having oppositelydisposed arms, the ends of which are located in said recesses when saidbar is in normal position, and means for locking said her in normalposition.

2. A plate provided with a recessed lug on each end and on oppositesides, in combination with a pivotally mounted bar having oppositelydisposed arms, the ends of which are located in said recesses when saidbar is in normal position, and means for locking said bar in normalposition, the opposing faces of the upset arms being recessed, thedeepest part of each recess cutting the axis of the pivot of said bar.

3. A plate provided with a recessed lug on each end and on oppositesides, in combination with a pivotally mounted bar having oppositelydisposed arms,the ends of which are located in said recesses when saidbar is in normal position, a bolt pivotally connected to said bar andextending through one of said lugs and a nut working on said bolt andadapted to engage the external face of said lying on a line lug to holdsaid bar in normal position,-the

extreme free end of said bolt being spread to prevent removal of saidnut therefrom.

4. A plate provided with a recessed lug onder, in combination with a barpivotally mounted ona pin passing through said perforation and providedwith oppositely disposed arms having their ends received in saidrecesses when said bar is in normal position and means for holdingsaidbar in normal position.

5. A plate provided with a plurality of recessed lugs, bar mounted formovement on said plate and having arms the respective ends of which areadapted to be received by the respective recessed lugs when said bar isin normal position, and said bar in normal posit-ion, each of said armsbeing adapted to receive an endless article when out of normal position.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
